Okay, lets do this! haha So, the FX120 that is uncovered has the autotrickler V1 attached to it. Back in 2018, A419 made the base for it because the OEM one was rather crudely 3D printed - the weight of the A419 base was a welcome upgrade.
Regarding your loaded question, currently, I only run H4350 in my ST because of the amount of H4350 I go through (260 rem, 6.5 man bun). For all other powder / calibers, I manually throw a charge with my Redding thrower and use my autotrickler. I may use the ST more in the future but it is a semi-recent acquisition (3 months or so). I like keeping it full of H4350 because I go through a lot of .264 rounds especially in the summer months.
I am right handed. Workflow after trimming / priming for my 338 is as follows assuming it isnt my first cartridge: Use the Redding thrower to give me a charge, place it on the scale (I purposefully adjust the initial throw so the charge is still trickling up rather quickly while I seat the bullet). Next, I take the charged brass and seat the bullet using the arbor press. By the time I am done putting the loaded round in the tray, the next charge is trickled up. I place the measured charge in the next piece of brass, throw another charge, and place the cup on the scale.... rinse and repeat. It should be noted that I do not throw all the charges (as one step) and then seat bullets. I hate having measured throws in brass without a hat on it. And, I find that just waiting for a charge is a tremendous waste of time....
For some calibers (5.56, 308, 500 SW, 300 blk, 8mm Mauser, 270 rem), I use the Zero for bullet seating but for precision rounds (338, 260, 6.5), I go inline seating w the arbor press as ive found seating pressure to be way more accurate / apparent / repeatable- the Zero is just ridiculously powerful.
I will include a pic of my setup to hopefully better explain but my workflow goes: Deprime on Zero, Tumble (Extreme Tumbler Rebel) - on a different workbench, Dry in a Frankford Arsenal dryer, Anneal in the AMP, Resize on 419, Mandrel on the 419, Trim on Henderson, Prime (RCBS Auto Primer to the left of that RCBS case prep center...cant see it in the pic), throw charges and seat bullet at same time (using Arbor or 419 depending on caliber).
It should also be noted that with my setup, I tried to separate the steps 'geographically' because I load with my buddy sometimes - case prep on the left bench, loading on the right bench. I also never load start to finish - I have about 15 of those sealable clear cereal containers you get from HomeGoods and just leave myself notes in them with where I left off / the next step. It has worked out really well so far.
All of that said, I am constantly reinventing my space for economy of motion. My advice would be get some T tracks from Rockler because having options to move equipment around is a game changer and your bench won't be swiss cheese by the time you figure out your flow.
